Answer:

[tex]x^2-y^2[/tex]

Step-by-step explanation:

Given the expression [tex](x+y)(x-y)[/tex]

We can distribute this using the FOIL technique

This would leave us with

[tex]x^2+xy-xy-y^2[/tex]

Then we can combine like terms to leave us with

[tex]x^2-y^2[/tex]

Steps:

(x+y)(x-y)

x^2-xy+xy-y^2

Multiplying the brackets together.

negative and positive= negative

= x^2-y^2

Answer is x^2-y^2
